Propane and Chlorine react in the presence of UV light to give 2-chloropropane and HCl. Estimate the enthalpy change of this reaction using the following bond enthaplies (KJ/mol) : C-H=+413, Cl-Cl=+243, C-Cl=+346 and H-Cl=+432.

Write equation, ensuring both sides are balanced.CH₃CH₂CH₃+ Cl₂→ CH₃CH(Cl)CH₃+ HCl (2.) Draw structural formula of all reactants ...

Explain why giant ionic lattices can conduct electricity when molten or in solution rather than as a solid.

In the solid phase the ionic lattice has no mobile ions as all the ions are fixed in place. However when dissolved in a solution or in the molten phase, the ionic lattice breaks down allowing the ions to ...
